Answer 1

First, find the product of the numbers:

• 3 · 7 · 13 · 37 = 10101

Now, rewrite the given expression as:

• x·10000 + y·100 + x + y·10000 + z·100 + x + z·10000 + x·100 + y =
• x(10000 + 100 + 1) + y(10000 + 100 + 1) + z(10000 + 100 + 1) =
• 10101x + 10101y + 10101z =
• (x + y + z)·10101 =
• (x + y + z)·3·7·13·37

Proved that the given expression is divisible by 3, 7, 13 and 37.
